CS387 - Alternator Voltage Regulator Darlington Driver

Download the CS387 datasheet PDF. This datasheet also covers the CS3341 variant, as both devices belong to the same alternator voltage regulator darlington driver family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • The CS3341/3351/386/387 integral alternator regulator integrated circuit provides the voltage regulation for automotive, 3-phase alternators. It drives an external power Darlington for control of the alternator field current. In the event of a charge fault, a lamp output pin is provided to drive an external darlington transistor capable of switching on a fault indicator lamp. An overvoltage or no STATOR signal condition activates the lamp output. The CS3341 and CS3351 are available in SO14 pac.
